APPARATUS FOR PURIFYING WATER.

SPECIFICATION forming part of Letters Patent Na. 411,292, dated September 1'7, 1389.

Application filed January 2, 1889. Serial No. 295,241. (No model-l To aZZ whom it may concern.-

lfle itknown that I, FREDERIC 1i. Moonn, a citizen of the United States, residing at'lloston, in the ccmnty of Hntiolk and State of Massachusetts, have in vented certain new and useful Improvements in Apparatus for Purifying \Vater, of which the follmving, taken in connection with the accompanying drawings, is a specification.

The object of my invention. is to produce an effective apparatusfor purifying water by distillingand aerating the same, so that. it will be almost, if not entirely, free from an imal, vegetable, or other impurities.

The invention consists of a boiler forvaporizin g the water, said boiler being connected to the upper end of a worm or coil situated in a condensing-vessel which is supplied with cold water, the other end of the worm being connected. to a pipe leading to an aerating vessel or jar provided with a number of holes at its upper end, and also fitted with a series of perforated shelves, through each of which the condensed water passes in small drops, so that every particle of the water comes into contact with the atmospheric airbefore it reaches the reservoir, from which it is drawn olfas required.

Referring to the accompanying drawings, Figure 1 represents a side elevation of a waoer-purifying apparatus embodying my invention. Fig. 2 is a vertical longitudinal section throughthe same. Fig. 3 is a view of one of the shelves in the acratirig-vessel,and Fig. 4 1s a view of the under sideof the cover for the same.

Y A represents a cylindrical boiler supported upon and heated by a gas-stove B.

a is the watersupply, and b a water-gage. The upper portion of the boiler is domeshaped, and is connected by a pipe 0 to the upper end of a worm or coil D, situated in a condensing-vessel E,Which is supported on the top of the boiler A by a perforated collar or stand F. The other end of the worm or coil D is connected by a pipe G to anaerating vessel or'jar H. The condensing-vessel E is kept full of cold water, which enters it by the supply-pipe c and escapes by the overflowpipe cl. It is also provided with a faucet e, by which it can be emptied when desired.

The'pipes a (I may, where practicable, be connected with the watenservice of thebuilding and provided with all necessary cocks and valves.

The upper portion ofthe aerating-"esselH is provided with a series of shelves J. These shelves are supported upon small lugs j, secured to the inner si de of the vessel .11, and the center of each shelf is formed dish-shaped, as shown, and they are also perforated with a number of small holes. The outer edges of the shelves are preferably turned up to prevent any water escaping over them, J n'st above the level of each. shelf a number of large holes A? are formed in the aerating-vessel 11, so that thc atmospheric air can pass freely through the same.

The cover 7: of the aerating-vessel H is provided near its outer edge with a number of holes and in its center it is fitted with a small strainer m, which-is so connected that it can be easily removed when required. The pipe G from the worm enters the cover above the strainer m.

K is a cock for drawing oif the purified water when required.

The aerating-vessel ll stands upon an icebox L, provided at its upper end with an aperture, so that the cold will come into direct contact with the bottom of the aerating-vessel ll, thereby more quickly cooling the purified water therein.

The operation is as follows: The igas-stov'e being lighted, the water in the boiler A is heated until steam is -generatedavhich passes up the pipe 0 to the top of the worm or coil D, through which it then passes to the pipe G. Cold water is admitted by the pipe 0 to the condensing-vessel E, and is caused to circulate around the worm and escape by the pipe d, thereby cooling and condensing the steam as it passes through the worm. The condensed water, after leaving the worm D, passes through the pipe G to the aeratingvessel H, which it enters at the cover and passes in small drops through the strainer m onto the upper shelf k, and thence through said shelf in small drops tothe g'next shelf, and so on until it reaches the lower; portion of the, vessel H, from which it can be? drawn off by the cock K. As the water passes from the strainer to the topshelf, and thence from shelf to shelf, it is constantly broken np into Small particles, apd as air is freely admitted through the holes 70 In every particle is 5 brought into direct, contact with the atmos'-' phere and becomes properly charged with ai r.

It willbe seen that water thustreated is purifled by evaporation and then aerated, thereby producing a water that is pure and at the same time agreeable'to the taste. Y

If desired, smallpieces of marble or other purifying or charging compounds may be placed in. the strainer m and on the shelves J,

thereby more effectuallyaeratingand pu rify- :5 ing the water as it percolatcs through the same.

Instead of heating the boiler A by a gasstove, it may be placed upon and be heated by an ordinary stove or range, and in places 20. Where steam is employedfor heating or other purposes the steam may be taken directly from the boiler used for producing said steam.

WVhat-I claim-as my invention is--' r p 1. An aerating-vessel provided with a se- 25.11% of dish-shaped perforated shelves at its upper end, and a series of holes through the 'wall of the vessel just above thelevel of each of theshelves for the admission of atmospheric air jointly with a water-distilling ap- 3o paratus, and a pipe connecting the distilling apparatus and the upper-end of the aeratingvessel, substantially as and fertile purposes set forth.

2. In a water-distilling apparatus,a boiler, a worm or cell communicating therewith and inclose'd within a condensing-vesselsupplied with cold water jointly with an aerating-ves selprovided with av series of perforated dishshaped shelves and holes for the admission of atmospheric air, and a strainer on the under 40 side of the cover, and a pipe connecting the cover with the worm for conducting the condensed water thereto, substantially as shown and described.

3. In a water-distillingapparatus,aboiler, a worm orcoil communicating therewith and inelosed within a condensing-vessel supplied with cold water jointly with an aerating-yessel having a series of dish-shaped perforated shelves at its upper end and aseries of holes through the wall of the vessel just above the level of each of the shelves for the admission of atmospheric air, an ice-box, and a pipe conto this specification, in the presence of two subscribing witnesses, on this 31st day of Deecm- FREDERIO n.
